Although Glazer's reign coincided with a glut of silverware - including five Premier League crowns and the 2008 Champions League title - he remained a hate figure for many supporters.

Fans have complained that Glazer's ownership model has forced United to spend millions of pounds servicing the club's debt - money which could have been spent in strengthening United's playing staff.

Nevertheless, Glazer found a consistent and vocal ally in Manchester United's legendary former manager Sir Alex Ferguson, who insisted the American had been "great" for the club.

"I am comfortable with the Glazer situation. They have been great," Ferguson said in 2012, a year before he announced his retirement.

"They have always backed me whenever I have asked them. I have never faced any opposition."

United fans pay muted respects

Manchester United fans paid muted respect to Glazer as deep resentment still lingers over his debt-ladened takeover.

Manchester United Supporters' Trust vice-chair Sean Bones said: "It would be inappropriate for me to make any comment about the death of Malcolm Glazer as I didn't know him or his family personally.

"However, as a supporter, I am aware of the detrimental effect the Glazers have had on the football club and the huge debt that has been placed on Manchester United.

"Malcolm Glazer wasn't a board member and his children are on the board, so I don't think that situation changes much."

Fans took to club forums to call for a respectful reaction.

One user on fan site RedCafe wrote: "say what you will... but he presided over the most successful period in the clubs history", while another urged fellow supporters to "keep it sensible", saying the death was "bound to be a flashpoint for some fans."

"I would hope most of our fans will be able to retain some level of civility, in spite of the general feeling towards what he and his family have done with regards to the clubs' finances," wrote one supporter, while another reflected on "a very strange year for our club."

Others highlighted to Glazer's succesful partnership with former coach Ferguson, who was able to carry out his job with little boardroom interference.
